How to Read Fluid Mechanics Equipment Specifications
When procuring fluid mechanics lab apparatus, the technical specifications sheet determines whether the equipment will meet your syllabus requirements, fit your lab space, and support the experiments you need to run. This guide explains the key specifications for each major category of fluid mechanics equipment.
Hydraulic Bench and Sump Tank
| Specification | Standard Value | Why It Matters |
|---|---|---|
| Sump tank capacity | 500–1000 L | Sufficient water reserve for simultaneous experiments |
| Pump flow rate | 30–60 L/min | Adequate head and flow for Bernoulli, pipe friction experiments |
| Pump head | 10–20 m | Sufficient for multi-floor setups and turbine rigs |
| Measuring tank | 100–200 L with overflow weir | For accurate volumetric flow measurement by timing |
| Frame material | 304 stainless steel or powder-coated MS | Corrosion resistance in wet lab environment |
Centrifugal Pump Test Rig Specifications
| Specification | Standard Value |
|---|---|
| Pump type | Single-stage centrifugal (single and multi-stage variants) |
| Motor power | 0.5–1.5 kW (3-phase, 415V) |
| Maximum head | 15–25 m |
| Maximum discharge | 15–30 L/min |
| Pressure gauges | Inlet (vacuum gauge) and outlet (pressure gauge), 0–10 bar |
| Flow measurement | Rotameter or measuring tank with stopwatch |
| Speed measurement | Digital tachometer, 0–3000 rpm |
Pelton Turbine Test Rig Specifications
| Specification | Standard Value |
|---|---|
| Turbine type | Pelton wheel (impulse turbine, horizontal shaft) |
| Number of buckets | 16–20 |
| Runner diameter | 200–300 mm |
| Nozzle | Single adjustable spear nozzle with jet deflector |
| Speed range | 0–1500 rpm (loaded), 0–3000 rpm (no load) |
| Load measurement | Rope brake or hydraulic dynamometer with spring balance |
| Supply head | 15–25 m (from overhead tank) |
Pipe Friction Apparatus Specifications
| Specification | Standard Value |
|---|---|
| Pipe materials | GI, MS, copper, PVC (4 pipe types for comparison) |
| Pipe diameters | 12 mm, 20 mm, 25 mm (3 diameters for friction factor comparison) |
| Pipe length | 2–3 m test section per pipe |
| Manometer type | Differential U-tube manometer (water-mercury or water-CCl₄) |
| Fittings included | 90° elbow, 45° bend, sudden expansion, sudden contraction, gate valve, globe valve |
Bernoulli’s Theorem Apparatus Specifications
| Specification | Standard Value |
|---|---|
| Test section | Convergent-divergent acrylic duct |
| Piezometer bank | 7–10 tappings along the duct length |
| Pitot tube | Stainless steel traversing pitot tube (0.5 mm dia) |
| Flow rate range | 2–20 L/min (adjustable by gate valve) |
| Material | Transparent acrylic test section; SS/MS frame |
What to Ask Your Supplier
- Can the equipment be customised to match your university’s specific syllabus experiments?
- Is the measuring range calibrated and certified?
- What are the utilities required (power, water, drainage)?
- Is a detailed experiment manual included, aligned to your curriculum?
- What is the warranty period and what does it cover?
